“…AgNPs have been considered as an alternative nanocatalysts to address these issues. The catalytic oxidation of organic dyes like methylene blue 26 and indigo carmine, 27 as well as small organic molecules such as styrene 28 and alcohols, 29,30 catalytic behavior in the oxidation of morin with H 2 O 2 was evaluated. 31 The green synthesis approach for the synthesis of AgNPs by the reduction of silver salts using biological extracts as reducing agents has been a hot research topic over the past couple of decades because of its significant advantages over chemical synthesis including simplicity, cheapness, slower kinetics, easy manipulation, and avoidance of the use of toxic and hazardous chemicals.…”

“…AgNPs have been considered as an alternative nanocatalysts to address these issues. The catalytic oxidation of organic dyes like methylene blue and indigo carmine, as well as small organic molecules such as styrene and alcohols, , has been performed by AgNPs; however, a single study in the literature on the oxidation of morin in the presence of AgNPs with H 2 O 2 as the oxidant was reported by Meijboom et al for the first time. In their study, poly(amidoamine)-capped AgNPs were synthesized and their catalytic behavior in the oxidation of morin with H 2 O 2 was evaluated …”

Herein, we present a facile and convenient method for the preparation of silver nanoparticles (AgNPs) in the presence of quercetagetin, a unique plant flavonoid, as a reducing and stabilizing agent. The nanoparticles (Que-AgNPs) were characterized using UV–vis spectroscopy, transmission electron microscopy, energy-dispersive X-ray spectroscopy, X-ray diffraction, and dynamic light scattering techniques. Que-AgNPs display a spherical shape and a crystalline structure. The size of Que-AgNPs was calculated to be 93 ± 0.4 nm in diameter with polydispersity index value of 0.3. Que-AgNPs were evaluated as nanocatalysts in the oxidative degradation of morin with hydrogen peroxide (H2O2). The catalytic degradation of morin was completed within 20 min, demonstrating excellent catalytic properties for Que-AgNPs. Kinetic studies revealed that the reaction follows pseudo-first-order kinetics and the apparent rate constant (k app) is positively correlated with the concentration of Que-AgNPs; however, k app is inversely associated with the morin concentration. Moreover, the cytotoxicity of Que-AgNPs was evaluated by the cell viability test considering two cell lines, i.e., HeLa and MCF-7. The results show that Que-AgNPs possess dose-dependent cytotoxic activity.

Gold and silver nanoparticles are nanoparticles that have been widely used in various fields and have shown good benefits. The method of nanoparticle biosynthesis utilizing plant extracts, also known as green synthesis, has become a promising method considering the advantages it has compared to other synthesis methods. This review aims to give an overview of the phytochemical compounds in plants used in the synthesis of gold and silver nanoparticles, the nanoparticle properties produced using plant extracts based on the concentration and structure of phytochemical compounds, and their applications. Phytochemical compounds play an important role as reducing agents and stabilizers in the stages of the synthesis of nanoparticles. Polyphenol compounds, reducing sugars, and proteins are the main phytochemical compounds that are responsible for the synthesis of gold and silver nanoparticles. The concentration of phytochemical compounds affects the physical properties, stability, and activity of nanoparticles. This is important to know to be able to overcome limitations in controlling the physical properties of the nanoparticles produced. Based on structure, the phytochemical compounds that have ortho-substituted hydroxyl result in a smaller size and well-defined shape, which can lead to greater activity and stability. Furthermore, the optimal condition of the biosynthesis process is required to gain a successful reaction that includes setting the metal ion concentration, temperature, reaction time, and pH.

“…The selective oxidation of aromatic alcohols to aldehydes is an important reaction in basic research and industrial processes. [1][2][3][4] Among aldehydes, benzaldehyde (BAL) is a versatile intermediate and highly-valuable chemical that is widely used in the pharmaceutical, dyestuff, food, cosmetic, and agrochemical industries. [5][6][7][8][9] However, the wide range of applications of benzyl alcohol (BOL) oxidation to BAL depends on improving its cost effectiveness and sustainability, which is intricately linked to the use of green oxidants, solvents, and catalysts.…”
